To make breadcrumbs or croutons: In a toaster or oven, toast the slices of bread until dry and crisp. Allow the bread to cool completely and then pulse in blender or tear/cut into bite size pieces.

Heat 1 tablespoon of olive oil in a pan over medium heat. Add the breadcrumbs and cook, stirring frequently, until evenly brown, about 5 minutes. Remove from heat and set aside on a plate or bowl.

Using the same skillet, heat the remaining 2 tablespoons of olive oil over medium heat. Add the garlic, anchovy filets, red pepper flakes, and lemon zest. Cook until fragrant and the garlic begins to brown.

Add the beans, cook until they warm, about 2-3 minutes. Stir in the Dijon mustard. Remove from heat.

Season with salt & pepper. Finish with lemon juice and parmesan cheese, if using. Top with breadcrumbs. Serve with love!
